Trying to Guess Next JP Event's Alts.
Basically, I was a bit bored and just thinking about the alts that could come to LostWord. Further notes are, Sekibanki released AFTER Kogasa, but they're still considered a pair, as is Cirno and Wakasagihime. So I think Kagerou would also get paired up with someone more popular than she is, who also could easily have commonality connection with. Tewi and Reisen are also possiblies, for this, as well as any of the wolf girls. Reisen is like, the secondary guess here.
For Iku, this is mostly because like I said, I think Lr Tenshi is the most likely to get a costume this event, and Iku like I said, is long overdue for an alt. I picked Suika because I don't think the idea of "Older Character looking after Younger Character" will actually be a theme, but if it is, Suika and Iku at least have the connection of Suika taking a place in Heaven for a bit.
Last one is mostly that I predict Tenshi and Nareko will get costumes, Momiji just feels like a fitting third character, but it's mostly a guess, as is the idea of a Yamame or Kisume alt. Could you imagine EX Kisume though, how would that even work lmao.
